Guarded Genius

Detects and locally tokenizes PII before it reaches ChatGPT.

Stop exposing private and business information to AI. Every time you paste an email, a client name, a contract detail, or a phone number into ChatGPT, that information leaves your device. Guarded Genius is a privacy extension that automatically detects sensitive information in what you type and masks it before it ever reaches ChatGPT, so you can keep using AI without giving away the details behind your questions. HOW GUARDED GENIUS PROTECTS YOU Before your message is sent, Guarded Genius scans it for personal and business information (names, email addresses, phone numbers, Social Security numbers, credit card numbers, locations, dates, ages, and more) and replaces each one with a safe placeholder. ChatGPT only ever works with the masked version, yet still understands your question and gives you a full answer. It just never sees who or what the question was really about. SEE YOUR REAL DETAILS IN A PRIVATE VIEWER When ChatGPT replies, the conversation stays masked. To read the answer with your original details, click the "See Unmasked Values" button. Guarded Genius opens a dedicated, read-only viewer on your device where everything you wrote is restored exactly as you typed it. In the viewer you can: • Switch between raw tokens and unmasked values with one toggle • See exactly which types of information were detected, with a count for each category • Copy the response with formatting, ready to paste into an email or document • Print the response or save it as a PDF The real values appear only in this private viewer, on your device. They are never sent back to ChatGPT. PRIVATE BY DESIGN: NO API, NO CLOUD, EVER Guarded Genius doesn't send your data anywhere to do this. There is no API call, no cloud server, and no third party in the middle. Detection, masking, and unmasking all run locally, inside your browser, on your own device. Nothing you type is ever transmitted, logged externally, or stored outside your computer. This isn't a privacy policy promise. It's how the extension is built. COMPLETE CONTROL, YOUR RULES Automatic detection covers the most common categories of sensitive data, but every person and business has their own list of things that matter: a company name, a project codename, an internal ID format. Guarded Genius lets you: • Add unlimited custom detection rules, including full regex pattern support • Import or export your rule set as a CSV file, so you can back it up or share a standard rule set across a team • Preview exactly what will be masked before every message is sent (debug preview mode) • Unmask any single item for one message only, or set it to always mask going forward • Reveal your original details in the private viewer with one click, then copy, print, or save them as a PDF • Download a local audit log of every masked token and its original value, stored only on your device WHO GUARDED GENIUS IS FOR • Anyone using ChatGPT who doesn't want to think twice before typing something personal • Freelancers and consultants handling client information in AI conversations • Enterprise and company employees who use AI tools at work and need to keep company and customer data confidential • Privacy-conscious users who want to see and control exactly what an extension does, not just trust a privacy policy WHY LOCAL-ONLY PRIVACY MATTERS Most "AI privacy" tools still route your text through their own servers to do the detection work, which means you're trusting a new third party with the exact data you were trying to protect. Guarded Genius has no backend, no API, and no account system. There's nothing to sign up for and nothing for anyone to breach, because your data is never sent anywhere in the first place.
